Broadcast-Communication Content Synchronization via Auxiliary Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for distributing content through a combination of broadcasting and communication channels face challenges in synchronizing and efficiently accessing content due to delayed timing in starting communication content reception, leading to increased processing complexity and delayed acquisition.
Innovation Solution
A transmission method that includes transmitting auxiliary information using a broadcast wave to synchronize content transmitted via both broadcast and communication channels, utilizing location and clock synchronization information to enable seamless playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If content is transmitted through both broadcast and communication channels, then content distribution capability is improved, but synchronization difficulty increases
Solution Approach 1:
A synchronization management module is introduced as an intermediary component that receives synchronization information from the broadcast channel and uses it to coordinate content acquisition from both broadcast and communication channels. This mediator handles the complex synchronization logic centrally, reducing the overall system complexity while maintaining multi-channel distribution capability.
Solution Approach 2:
The system acquires synchronization information from the broadcast channel before acquiring content from the communication channel. This preliminary action establishes a reference timing framework in advance, allowing subsequent content acquisition and playback to be synchronized more easily without requiring complex real-time coordination.
2Adaptability or versatility
If communication channel is used for content distribution, then transmission flexibility is improved, but reception timing delay increases
Solution Approach 1:
The system performs preliminary acquisition of synchronization information from the broadcast channel before accessing communication channel content. This advance preparation establishes timing references that enable the communication channel content to be received and synchronized with minimal delay, combining the flexibility of communication channels with the timing reliability of broadcast.
3Manufacturing precision
If synchronization information is acquired from broadcast channel, then playback synchronization is improved, but information acquisition complexity increases
Solution Approach 1:
The system extracts only the essential synchronization information (timing references and synchronization markers) from the broadcast channel, separating this critical function from other broadcast content. By taking out only the necessary synchronization data rather than processing all broadcast information, the system achieves accurate playback synchronization while minimizing acquisition complexity.

AI summary
According to one aspect of the present disclosure, a transmission method for enabling transmission of content using a broadcast and a communication channel includes: transmitting playback control information and service information using at least the broadcast wave, the service information being information for playing back content transmission using the broadcast and content transmission using the communication channel when the content is transmitted using the broadcast and the communication channel. The service information includes the content and location information that indicates a location for acquiring meta-information on playback control of the second content. The playback control information includes indexes of a relationship between the first content data and the second content data.
